Oxolotl is the Nahuatl (Aztec language) word for the Mexican salamander, Ambystoma mexicanum. The axolotl is a fascinating amphibian native to the ancient water systems of Lake Xochimilco and Lake Chalco in Mexico City. It's known for its unique ability to regenerate lost body parts, including limbs, spinal cord, and even parts of its brain. Axolotls are also popular in scientific research due to their regenerative capabilities and their unique physiological features. In recent years, they have gained popularity as pets and are bred in captivity worldwide.
